CHAIR.

Specification of Letters Patent.

Patented Apr. 5, 1919.

Application filed October 28, 1908. Serial No. 459,614.

To allwhom it may concern:

Be it known that I, EDWARD VRBA, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Improvement in Chairs, of which the following is a specification.

This invention relates to chairs and more in particular to reclining chairs, the object being to provide a foot rest in connection with the pivoted baok whereby when the back is thrown rearwardly, the foot rest will be thrown forwardly.

Another object of the invention is to provide a foot rest which is so constructed that when in a folded position, it will be under the seat of the chair out of the way.

A still further object of the invention is to provide very'novel means for operating the foot rest which is so connected to the pivoted back that after the foot rest has been extended and the person wishes to withdraw the same, it is only necessary to remove the weight off of the back and the back and foot rest will be thrown back into normal position.

A still further object of the invention is to provide a foot rest which is exceedingly cheap and simple in construction and one which is provided with operating means which are so mounted and connected to the rest and back of the chair that it is not likely to get out of order in use.

With these various objects in view, my invention consists in the novel features of construction arrangement and combination of parts hereinafter described pointed out in the claims and shown in the accompanying drawings, in which Figure l is a vertical section through my improved chair. Fig. 2 is a horizontal section taken on line 2-2 of Fig. 1. Fig. 3 is a perspective view of the operating arm and links, detached. Fig. 4 is a section taken on the line 44 of Fig. 2. Fig. 5 is a section taken on line 55 of Fig. 2.

In the drawings, A indicates a chair which is provided with the ordinary seat frame A and pivoted back frame A which is preferably pivoted on a rod as clearly shown whereby it will be held in its proper position and yet be capable of moving freely between the arms of the chair. Secured longitudinally in-the seat frame are a pair of guide bars B which are provided with grooved inner faces forming guideways in which are mounted the reduced ends of a guide member C on which is pivotally mounted the inner pair of cross levers of lazy tongs D, the outer pair of levers of which are pivotally connected to the under side of a foot rest E which is pro vided with guide arms E mounted in guideways formed in the seat frame. The inner ends of the lazy tongs D are pivotally mounted in the slot formed in the back board of the seat frame and the back board is provided with a smaller slot in which is pivotally mounted one end of a coil spring F the free end of which carries a clevis G which is pivotally connected to the guide strip and lazy tongs whereby the foot rest will be drawn back into position after it has been extended as will be hereinafter fully described.

Secured to the rear of the pivoted back frame A is an arm H which is provided with a bifurcated lower end between which is pivotally mounted a link H over the free end of which is mounted the bifurcated end of a clevis I which is pivotally connected to one of the pivot pinsof the cross levers of the lazy tongs as clearly shown, and it will be seen that as the persons weight is thrown upon the back of the chair, the clevis will be thrown forwardly so as to eX- pand the lazy tongs which will throw the foot rest out in advance of the chair in position to receive the feet. It will be seen that I have provided the lazy tongs with a pair of enlarged cross levers which enables the rest to be thrown forwardly to a greater extent and at the same time allows the rest to be drawn inwardly by the spring. The lazy tongs rest and are supported by the guide strips so that they will be held in a proper position at all times, and it will be seen that when the users weight is thrown upon the back frame, the foot rest will be thrown forwardly so as to expand the spring and when the weight is removed from the back frame, the spring will draw the foot rest and back frame into its normal position so that the rest will be out of the way. It will be seen that I have provided a rest which is so constructed that when not in use, it will rest up against the front of the seat frame out of the way. While I have shown and described the lazy tongs constructed in this peculiar manner, it Will of course be understood that any suitable form of lazy tongs can be employed.

hat I claim is 1. The combination with a chair provided with a pivoted back frame, of guide strips provided with grooved inner faces secured under the seat frame, a guide member slidably mounted in the grooves of said guide strips, a foot rest provided with arms slidably mounted under the seat frame, lazy tongs arranged on said guide strips having their front ends connected to said foot rest and their rear ends connected to said seat frame, said lazy tongs being connected to said guide member, a coil spring connecting said guide member to said seat frame, a bifurcated arm carried by the back frame, a link mounted in said arm, and a clevis connected to one of the joint pins of the lazy tongs provided with a bifurcated end in which the free end of said link is pivotally mounted.

2. The combination with a chair provided with a pivoted back frame, of guide strips secured to the seat frame, a foot rest slid ably mounted in said seat frame, lazy tongs connecting said foot rest to the seat frame, a guide member connected to one of the pivot pins of the lazy tongs, a spring connected to said guidemember having its free end connected to the rear of the seat frame and a bifurcated arm connected to a clevis carried by one of the pivotpins of the lazy tongs by a link.
